Selective adsorption of oppositely charged PNIPAAM on halloysite surfaces: a route to thermo-responsive nanocarriers.

2018

Halloysite nanotubes were functionalized with stimuli-responsive macromolecules to generate smart nanohybrids. Poly(N-isopropylacrylamide)-co-methacrylic acid (PNIPAAM-co-MA) was selectively adsorbed into halloysite lumen by exploiting electrostatic interactions. Amine-terminated PNIPAAM polymer was also investigated that selectively interacts with the outer surface of the nanotubes. The adsorption site has a profound effect on the thermodynamic behavior and therefore temperature responsive features of the hybrid material. The drug release kinetics was investigated by using diclofenac as a non-steroidal anti-inflammatory drug model. The release kinetics depends on the nanoarchitecture of th…

On the formation of inclusion complexes at the solid/liquid interface of anchored temperature-responsive PNIPAAM diblock copolymers with γ-cyclodextr…

2017

The thermal responsive behavior of adsorbed layers of diblock copolymers of poly(N-isopropylacrylamide) (PNIPAAM) and poly((3-acrylamidopropyl)trimethylammonium chloride) (PAMPTMA(+)) with γ-cyclodextrin (γ-CD) at the solid/liquid interface has been investigated using three in situ techniques: null ellipsometry, quartz–crystal microbalance with dissipation monitoring, and neutron reflectometry. The measurements provided information about the adsorbed amounts, the layer thickness, hydration and viscoelastic properties, and the interfacial structure and composition. The copolymers adsorb to silica with the cationic PAMPTMA(+) blocks sitting as anchors in a flat conformation and the PNIPAAM ch…

Alla ricerca dei fattori rilevanti nell’adozione dei sistemi di gestione della performance nelle amministrazioni pubbliche territoriali. L’analisi di…

2013

La ricerca scientifica ha dimostrato che la gestione della performance nelle amministrazioni pubbliche sta oggi spostando il proprio focus dalla mera attività di raccolta e rendicontazione di dati alla generazione di informazioni atte a supportare la formulazione di decisioni. L’analisi comparativa dei casi di studio analizzati in questo articolo mira ad identificare i fattori critici sottostanti alla progettazione e all’utilizzo dei sistemi di gestione della performance nelle amministrazioni regionali. Da questa analisi emerge che alcune variabili risultano essenziali ai fini di un’efficace adozione dei sistemi di performance management. Tra queste variabili sono annoverabili: il ruolo del…

Modern Impressionist or Idyllic Genre Painter? Zorn’s European Fame from an Italian Perspective

2013

This article examines Zorn's international fame (France, Germany) and then focuses on the Swedish painter's controversial reception in Italian media (Vittorio Pica, Ardengo Soffici).

«If you wrong us, shall we not revenge?»: la Shoah in scena

2020

Review on a short essay by Cynthia Ozick, Who Owns Anne Frank? The essay, published in 1997, was translated into Italian in 2019. The contribution start from Ozick's text to reflect on the genesis of Anne Frank’s book and on the presence of the Shoah in contemporary culture.

Lessons from uncertainty on antifungal treatment in ICU

2017

We read with great interest the Editorial from Moghnieh et al. on the EMPIRICUS trial and antifungal use in intensive care unit (ICU) (1). Authors described nicely the trial and some background evidence on untargeted antifungal treatment in non-neutropenic critically ill patients in ICU (2,3). However, we believe that some points may be further clarified. First, it may be useful to cite the study from Knitsch et al. among those evaluating empiric antifungal treatment in ICU (4). Knitsch et al. enrolled 252 critically ill patients with localized/generalized intra-abdominal infection either of community or of nosocomial origin requiring emergency surgery.

Untargeted Antifungal Treatment Strategies for Invasive Candidiasis in Non-neutropenic Critically Ill Patients: Current Evidence and Insights

2017

Purpose of Review: The purpose of this study was to provide an overview and insights on important new concepts on untargeted antifungal treatment strategies, namely prophylaxis pre-emptive and empiric treatments for the management of invasive candidiasis (IC) in non-neutropenic critically ill patients. Recent Findings: Recently, clinical practice guidelines provided recommendation for the management of IC. However, results from recent trials and systematic reviews questioned the effect of untargeted antifungal treatment strategies, especially in terms of survival benefits in non-neutropenic patients, even with septic shock. Summary: Widespread use of untargeted antifungal treatment strategi…

What Is the Most Recent Evidence on the Prevention and Early Treatment of Invasive Fungal Infections in Nonneutropenic Critically Ill Patients?

2017

: Invasive fungal infections (IFIs) are associated with high morbidity and mortality in intensive care units. Candida species are the most important fungal pathogens and among the most frequent causes of infection in critically ill patients. Studies have evaluated the correlation between the onset of antifungal treatment and survival. However, definitive diagnosis of IFI is time-consuming in clinical practice. Antifungal prophylaxis and preemptive or empirical treatments are among therapeutic strategies to prevent or treat early fungal infections in selected patients. Recently, new evidence from randomized controlled trials and systematic reviews has been published. Moreover, new clinical p…
